After a conversation on another forum, I now plan to request Duo from Duolingo slash fic the next time I do Yuletide. (But who would be the other character? The bear who drinks beer? The rhinoceros that the man tried to play with? Other?)

(Seriously, I've found Duolingo very helpful for picking up the basics of other languages; it's not enough to make one fluent, but it's enough of a grounding to build from.)
